Application filed May 14, 1907. Serial no. 373,539.

- To all whom it may concern:

Be it known that I, JACOB FELBEL, citizen of the United States, and resident of the boroug i of Manhattan, city of New -York, in the county of New York and State of New York, have invented certain new and useful Improvements in Type-\Vriting Machines, of which the following is a specification.

My invention relates to typewriting machines and more particularly to tabulating mechanism for such machines.

One of the main objects of'iny invention is to provide separate means at the keyboard of the machine; and preferably the. ordinary space key of themachine, for effecting a release of the carriage after the .tabulating inechanismlias been operated.

To the above and other ends which will hereinafter appear my invention annals/ts in the features of construction, arrangements at parts and combinations of devices described in the following specification and/particularly pointedout in the acconip anying claims.

In the accompanying drawings, wherein like reference charactersindicate corresponding parts in the different views, Figure 1 is a vertical front to rear sectional view, taken on a line s -x in Fig. 3 and looking in the direction of the arrow at said line, of a typewriting machine equipped with the devices of my invention, parts of the machine being omitted. Fig. 2 is a rear elevation of the same, the rear cross-plate of the base and a portion of the top plate being sectioned. away. Fig. 3 is a plan view of the machine with parts omitted and parts'broken away. Fig. 4 is an enlarged detail perspective view showing portions of the means for effecting the release of the carriage through the space key. Fig. 5 is a like view of another form of construction embodying my invention. Fig. 6 is a fragmentary-detail top plan view, partly in section of the switch shown in Fi 5 and part of the member which carries t;

I have shown my invention applied to a 1 Monarch machine, although it should be understood that the invention may be applied to other-styles of writing machines.

The frame of the machine comprises a base -1 having'a cover late 1%,..corner posts 2 and,

'platen'd is mounted in a carriage which comprises end plates 5 and a a top plate 3.

cross-bar 6 with oppositely disposed grooved tracks 7 formed thereon. Fixed tracks 8 typ ewriting Specification of Letters Patent.

have oppositely disposed grooved faces for cooperation with anti-friction balls 9 which are received between the grooved faces of the tracks 7 and 8 and'support the. carriage in its movement from' side to side of the machine. A feed rack 10 is connected to the rear ends of arms 11 pivoted at 12 to the end plates 5. of the carriage. The feed rack meshes with a feed pinion 13 operatively connectedthi'ough a shaft 13 to an escapeinent wheel 14 with which feed dogs 15 cooperate. The feed dogs arc carried by a dog rocker 16 pivoted to a depending bracket plate 17 and provided with a forwardly extending arm 18 pivotally connected at 19 to a depending link. 20. The lower end of the link is pivoted at 21 to a rearwardly extending arm 2 formed as a part of the universal bar frame which, as shown in Fig. 3, comprises the rearwardly extending arm 22, a universal bar 23, side arms 24, a rock shaft 25 pivoted at 25 and forwardly extending arms 26. The universal bar proper 23 extends beneath key levers 27 to be acted upon by the depression of any of said key levers and effect an operation of the escapement mechanism in the usual manner. A space key 28 is connected at its ends to forwardly extending arms 29 mounted to vibrate on a pivot rod 30, and connected by a cross-barf31 secured at the rear end portions thereof. Each of the arms 29-extends rearwardly beyond the pivot rod 30 and is provided with a set screw 32 which is adapted to cooperate with its associated arm 26 on the universal bar frame. The space key or bar 28-, the arms or levers 29 and the cross bar 81 constitute a rectangular space key frame. A depression of the space key is effective to rock the universal bar frame and thus actuate the escapement mechanism.

the machine is carried by a lever 37 pivoted /at 38 to a depending stud or bracket 2-39 in Each of the key levers 27 is connected in the the base of the machine and having a rearwardly extending arm 40, provided with a spring 41, by which the key lever and the parts connected therewith are restored to normal position. A sub-lever 4-2 is pivoted upper end 70, as indicated in Fig. 1.

at its forward end, as at 43, to a stud 44 inwardly projecting from the base of the 1nachine. The sub-lever'is connected to the tabulator key lever bya pin and slot connection, the pin 45 projecting from the side of the tabulator key lever and extending into the slot 46 in the sub-lever. The rear end of the sub-lever is pivotally connected at 47 to an upwardly ex tending link 48 which passes through openings in the cover plate 1 and in the top" plate 3 and is pivotally connected at its upper end, as at 45), to a crank arm 50 so cured to a rock shaft- 51. in bearings in bracket arms 53 which project rearwardly from brackets 54 to which the fixed carriage rails are secured. The rock shaft 51 is provided with adjustable column or tabulator stops 55 bifurcated for engagement with slots 56 on the rock shaft. Each of the column stops hasan engaging portion 57 for cooperation with a tabulator stop 58 secured by screwsb.) to the carriage.

By depressing the tabulator key 36, the sublever 42 will be depressed, thereby pulling down on the link 48 and rocking the column stop bar or rock shaft 51 to bring the column steps into position where they are adapted to moperate with the stop 58 on the carriage and to arrest the carriage at its proper columnar position when the carriage is released. from its cscapement mechanism.

in accordance with my present invention 1 provide separate means at the keyboard of the. machine for effecting the release of the carriage after the tabulator stops have been brought into cot'i 'icrative relation or into a relation where they will co-act to arrest the carriage after it is'released, such" separate means being actuated independently of the means for bringing the tabulator steps into .coo 'ierative relation. A bracket arm 60 projects upwardly and rearwardly from the right-hand end bar 24 of the universal bar frame to which said arm is secured by a screw 61. The rear free end of the arm 69 extends above a lateral projection 62 of a depending linker rod 63 which extends through an opening in the cover plate 1 by which the lower end of the rod is guided. The upper end of the rod 63 is pivotally connected at 64 to a lever 65 pivoted at 66 to a depending stud or bracket 67 which projects from the top plate of the machine. The inner end of the lever 65is pivoted at 68 to a carriage releasing device 69 bifurcated as shown in Fig. 2 to straddle the bearing for the shaft 13 of the escapement wheel, the releasing device being bent forwardly at the The flat faces f rmed by the bent portions 79 extend on op osite sides of the feed pinion and beneath t 1e feed rack, as shown in Fig 1. It will be understood that when the rod 63 is moved ,downwardly, an upward movement Will, be transmitted to the inner end of the The shaft 5] turns ford a movement of the universal bar frame and the arm 60'without actuating the carriage release, so that the carriage release mechanism is normally disconnected from the space key and the parts controlled thereby. The tabulator key lever 37 is pro vided with a cam 73, the inclined face 74 of which adapted to cm") )erate with the righthand end 75 of gee-cal ed switch or lever 76. This lever is pivoted by a headed screw 77 to a block 78 and is normally ressed into contact with a stop pin 78. y a spring 78. The block 78 is provided withv a spindle 79 that is received in-abe-aring opening in the plate 1 and is threaded at its upper end for securemcnt by nuts 80. bears on the latel and supports the block 78 in place, a though it is free to turn on its vertical axis or s indie 79. The block is held in the norma. position by a spring 81 secured at one end to the plate 1 and at the other end to the block From what has been said it will be understood that the leveror switch 76 has a pivotal movement in two directions, one movement being around its horizontal pivot 77 and the other movement being with the supporting block around the vertical pivot 79 of said block. The stop pin 78 rojects from The lowermost nut the block 7 S and acts to limit t 1e movement of the lever or switch 76 in one direction, but permits adownward movement of the inner end of the switch or lever from itsnormal position against the pressure of its returning spring 78' their the tabulator key lever 37 is depressed the inclined face 74 of the cam carried thereby is brought into engage= ment with the right-hand end 75 of the switch lever. Downward movement of the end 75 is prevented by the engagement of the opposite arm of the lever with the stop 78*, so that the cam is effective to turn the switch or lever and the block which supports it around the vertical pivot 79 of sair block.

The effect of this movement is. to interposc the filler or block-like end 82 of the'switch between the rear freeendof the arm 60 and the projection 62 on the link or red 63, thus practically filling the space between these parts and eliminating the lost motion which normally exists between them. The parts are so arranged that the operative connection between the space key and the carriage releasing mechanism is formed when the tabu1at' iar ing stops are brought into cooperative relation by the depression of the tabulator key lever 37. \Vhcn the switch-lever is thrown into working position, the end 75 is moved rearwardly beyond the cam face 74, so that said end takes a position against the rear vertical face 73 ofthe cam member 7 3 and at the lower portion thereof, and is held against said face by the returning spring 81 provided for the swivel-block 78. While pressure is still maintained on the tabulator key, to hold the stops interposed one in the path of another, the ordinary carriage space key 28 is depressed, thereby effecting a downward movement of the arm 60 connected to the universal bar frame, and the effect of this movement is to pull down the rod 63 through the intermediate switch 76 which at this time turns on its pivot 77, the end or arm 75 of the switch lever riding up on the vertical face or end 73 of the member 7 3 which keeps the filler 82 interposed during the carriage releasing movement. The pulling down on the rod 63 is effective to elevate the feed rack and thus release the carriage for rapid movement leftward. After the carriage has been arrested by the tabulating-mechanism and the keys released, the key-actuated parts will berestored to their normal positions and the operative connection between the space key and the carriage releasing mechanism will be automatically broken by the block 78 returning to itsnormal position and withdrawing the switch from between the arm 60 and the projection 62, as shown in Fig 4.

In the other form of construction shown in Figs. 5 and 6, the arm 60 connected with the universal bar frame, is provided with a switch 7 6* ivoted thereto at 83 to turn on a vertically (fisposed axis The switch has a projection 84 which bears against the arm 60 and limits the movement of the switch relatively to said arm in one direction. A

spring 85 is carried by the arm 60 and bears at its free end against the switch to maintain itin the normal position, that is, to the left of the projection 62 on the pull rod 63 of the carriage releasing member, as seen in Fig. 5.

' The tabulator key lever 37 carries a laterally projecting cam 7 3' provided with an inclined face 74 which is adapted to cooperate with the switch 76 to turn it around its ivot 83 and to bring it into cooperation witii the rejection 62. Thus when the tabulator key ever 37 is depressed to bring the tabulator steps into co61peration,-the cam 73 moves 55 feed rack down with the ey lever and ca-ms the switch .76 to the right, (as the parts are shown in Fig. 5) thereby bringing the switch above the projection 62 and effecting an operativeconnection between the space key and the carriage releasing mechanism, so that when the space key is depressed the 'rod 63 will be pulled down by the switch 76 to elevate the and thus release the carriage from 'releasing movement.

From the foregoing description it will be understood that in both of the constructions described the switch 76 or 76" is adapted to travel with and independently of the part which carries it; that the operation of the tabulating devices effects said independent movement of the switch to bring about an operative mechanical connection between the space key lever and the carriage releasing mechanism; and that the release of the carriage is effected by the ordinary space kcy'of the machine. Furthermore, it will be understood that it is necessary to actuate the tabulating mechanism to properly position the stops one in the ath of another before the carriage can he re eased by the space key and to maintain the stops in such position by pressure exerted upon the tabulator key unmechanism, but that this break is temporarily repaired, so to speak, by the operation of the key lever of the tabulating mechanism.

Any construction of tabulating mechanism, escapement mechanism and s ace key mechanism may be employed, anr various changes may therefore be made without departing from my invention.
